Installing Unreal under an administrator but it's showing up with "install" in the users accounts.

At work we installed Unreal under the computer admin account but when we’re in user accounts it’s coming up as "install’ with the 4.19.2. When you click on the install it shows the install location but says, “Directory must be empty”. I’m pretty sure this was the protocol I used to install previous versions of Unreal also as I have 4.14.3 up to 4.18.3 installed and access them fine. Did I forget to do something correctly?
